Year:2012 to 2017. The all new ACCEL Stealth Supercoil is the hottest looking and best performing ignition coil on the market. We've taken proven automotive technology and adopted it to the Harley Davidson Sportster engine.
They came very fast. My 2015 Mustang Ecoboost has way is accelerating quicker. A way better idle. I didn't think I would notice any difference. They are way better than the stock coils. I did put Brisk plugs and changed out NGK iridium plugs . NGK plugs kept fouling out gapped .028. Plugs and coils change and my car is performing excellent. NGK plugs are not as great as everyone say. Brisk are great. Motorcraft products aren't great either. Upgrade with Accel coils and Brisk plugs. It makes a big difference.
